A match is not deterministic #20

Closed merovingien closed 11 years ago

With the same data at start time, two consecutive matches are not identical, even without use of randomness!

Data in entry :

Result: The about 1000 first rounds are identical, and at a moment, there is one difference.

This issue was caused by the use of a set of pointers to report neighborhood. The memory allocation is not deterministic, so items in the set were not always present in the same order.

Now neighborhood is returned as a list of item pointers, which preserve the order of insertion. The python handler has also been updated to return a list of items. Player's scripts should not be impacted.

The bug is fixed by commit e29b36b
